Nissan Latio Thermostat Malaysia
Latio thermostat failures are uncommon but occur on high-mileage units. A stuck-closed thermostat causes the engine to overheat rapidly; stuck-open means the engine runs cold, increasing fuel consumption and wear. On the N17, the thermostat is typically replaced as part of the housing assembly. Symptoms of stuck-open: temperature gauge stays low after warm-up, heater doesn't produce warm air. Replace proactively at 100,000 km during a major service if the coolant is being changed.

Latio Thermostat Service
- Replace at 80,000 km or if temperature gauge reads abnormally
- Stuck open = never reaches operating temp, poor fuel economy and heater output
- Stuck closed = rapid overheating — do not drive, tow to workshop
- Use OEM Nissan thermostat — cheap units fail quickly in Malaysian climate
